In South Dakota, person devoid of charms ran (8)
I believe the answer is:
smuggled
'ran' is the definition.
(I've seen this before)
'in south dakota person' is the wordplay.
'in' is an insertion indicator.
'south dakota' becomes 'sd'.
'person' becomes 'muggle' (I can't justify this - if you can you should believe this answer much more).
'sd' enclosing 'muggle' is 'SMUGGLED'.
'devoid of charms' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for smuggled that I've seen before include "Moved illicitly" , "Illegally distributed" , "Ran contraband" , "avoided duties" , "Brought goods into country illegally" .)
